Russell Brand and Katy Perry are heating up. The womanizing actor, who first locked lips with the “I Kissed a Girl” singer at an MTV Video Music Awards after-party, recently texted her a love poem he wrote himself, according to a friend. “It was cute,” our source says. “And the best part is that Katy responded by sending him a topless photo of herself.” A rep for Perry didn’t get back to us.
